Carrying the ISO designation LT16ER14UNCB and manufactured in grade KC5025, this insert features a PVD-applied TiAlN coating that supports extended tool life in demanding materials. The 3\/8-inch (9.53 mm) inscribed circle and 0.1430-inch thickness conform to standard ER insert geometry, making it a direct fit for compatible laydown threading toolholders. It is installed by machinists and CNC operators performing external thread turning on lathes and turning centers.\u003c\/p\u003e\n\u003cp\u003eThis insert is suited for threading operations on steel, stainless steel, cast iron, superalloys, and titanium. The CB chipbreaker geometry helps manage chip flow during external UN thread profiling. Typical applications include production threading on turned components in job shops, aerospace, oil and gas, and general manufacturing environments where consistent thread form and insert-to-insert repeatability are required.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eInsert style ER, size code 16, ISO designation LT16ER14UNCB in grade KC5025\u003c\/li\u003e\n  \u003cli\u003ePVD TiAlN coating for wear resistance across steel, stainless, cast iron, superalloys, and titanium\u003c\/li\u003e\n  \u003cli\u003e14 TPI right-hand external UN thread form with CB chipbreaker\u003c\/li\u003e\n  \u003cli\u003e3\/8-inch inscribed circle with 0.1430-inch thickness to ER laydown insert standard\u003c\/li\u003e\n  \u003cli\u003eHole diameter of 0.1551 inches (3.94 mm) for secure clamping in toolholder\u003c\/li\u003e\n  \u003cli\u003eCutting edge to theoretical edge length of 0.0470 inches; face of insert to tip centerline 0.0590 inches\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or standard production insert for laydown threading toolholders accepting size 16 ER-style inserts with a 3\/8-inch inscribed circle.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by a qualified machinist or CNC operator with the machine in a fully stopped and locked-out state before changing inserts. Seat the insert fully in the toolholder pocket and torque the clamping screw per the toolholder manufacturer specifications. Inspect the seating surface and pocket for chips or debris before installing a new insert. Handle carbide inserts carefully to avoid chipping the cutting edges prior to use.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: ER\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Size Code\u003c\/strong\u003e: 16\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eISO Code\u003c\/strong\u003e: LT16ER14UNCB\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: KC5025\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: TiAlN (PVD)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Type\u003c\/strong\u003e: External\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThreads Per Inch\u003c\/strong\u003e: 14\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChipbreaker\u003c\/strong\u003e: CB\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 3\/8 inches (9.53 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.1430 inches (3.44 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 0.1551 inches (3.94 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Edge to Theoretical Edge Length\u003c\/strong\u003e: 0.0470 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFace of Insert to Tip Centerline\u003c\/strong\u003e: 0.0590 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Materials\u003c\/strong\u003e: Steel, Stainless Steel, Cast Iron, Superalloys, Titanium\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.0099 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23291804\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: KENNAMETAL\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 1712570\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51739949695282,"sku":"1712570","price":620.18,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/4af4a7112cdf0b6a519196bfb5a3e859.jpg?v=1788820659","url":"https:\/\/voomisupply.com\/products\/kennametal-1712570-threading-insert-14-tpi-un-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
